Reliable moisture protection with self-adhesive sealing tape
Sealing tape is an essential component for creating waterproof and durable joints in moisture-prone areas. Whether you are working on a bathroom renovation, sealing around windows, or protecting drywall, a high-quality tape prevents water ingress and subsequent structural damage.
Thanks to its self-adhesive properties, application is straightforward and efficient. It provides a secure barrier against moisture, ensuring that your building materials remain dry and protected over the long term.
Our range of Dalsys sealing tapes
In our assortment, you will find premium self-adhesive sealing tape from the trusted manufacturer Dalsys. These tapes are supplied in convenient 5-metre rolls, making them ideal for both small repairs and larger renovation projects.
To accommodate different joint widths and specific project requirements, we offer the tape in a clean white finish and various dimensions. You can choose between sizes such as 1.1x1.1 cm, 1.8x1.8 cm, 2.6x2.6 cm, and 2.8x2.8 cm, ensuring a perfect fit for any gap or corner.
Choosing the right sealing tape for your project
When selecting the appropriate sealing tape, it is crucial to measure the width of the joint or gap you intend to cover. A tape that is too narrow may not provide adequate protection, while one that is too wide could be difficult to apply neatly in tight corners.
Our self-adhesive options are designed for strong, immediate adhesion on clean, dry surfaces. Depending on the chosen width, prices for a 5-metre roll range from approximately £13.99 to £15.99 (as of 2026), offering a cost-effective solution for professional-grade moisture protection.
Frequently Asked Questions about sealing tape
How do I prepare the surface before applying self-adhesive sealing tape?
For optimal adhesion, the surface must be completely clean, dry, and free from dust, grease, or old silicone residues. Wiping the area with a suitable solvent or alcohol-based cleaner ensures a secure and lasting bond.
Can sealing tape be used in shower enclosures?
Yes, high-quality sealing tape is specifically designed for wet areas such as shower enclosures, bathtubs, and sinks. It creates a waterproof barrier that effectively prevents water from seeping into the underlying structure.
Is it possible to paint over the sealing tape?
Most standard self-adhesive sealing tapes are not designed to be painted over, as the flexible material can cause the paint to crack or peel. It is recommended to choose a tape colour that matches your existing decor, such as our versatile white options.
How long does self-adhesive sealing tape last?
When applied correctly to a properly prepared surface, self-adhesive sealing tape offers excellent durability and can last for many years. Its mould-resistant properties help maintain a clean appearance and reliable function over time.
Can I cut the tape to a specific length?
Absolutely, the tape can be easily cut to your required length using a standard utility knife or a pair of sharp scissors. This allows for precise application, even in complex corners or around fixtures.
Summary: Secure your joints effectively
Investing in high-quality sealing tape ensures that your bathrooms, kitchens, and drywall constructions remain safe from moisture damage. With the right preparation and our reliable self-adhesive options, you can achieve professional, long-lasting results.
